A friendly puzzle with some cheeky variant diversity that avoids saturating the screen. Variants are all common, nothing groundbreaking with the rules. Enjoy!
Rules:
Normal sudoku rules apply.
Killer Lines: Digits along marked diagonals sum to the digit outside the grid.
Slow Thermo (Grey): Digits stay the same or increase in value as you move from the bulb to the tip.
Between lines (Orange): Digits along a between line must be between the digits at the ends of the line.
Arrows: Numbers along the arrow sum to the number in the circle.
X: Cells joined by an X must sum to 10 (Not all X's are given).
Cells with a red circle must be an ODD digit.
Let the fuelling begin!
Solution code: Row 8 from left to right.
